摘要

基于传统的SIFT特征点匹配方法和图像像素级融合的思想

提出一种改进的SIFT特征点匹配的图像拼接算法.首先该算法在特征提取的过程中加入Harris角点算子

筛选出鲁棒性较强的点; 其次采用基于圆形窗口的48维向量来进行特征降维

并借助匹配特征点对之间的几何一致性来对特征点进行粗提纯

提高算法运行效率; 最后采用重叠区域线性过渡融合算法对图像进行平滑过渡

消除拼接缝隙.实验验证了该算法的鲁棒性和快速性.

Abstract

Based on traditional SIFT feature point matching method and image pixel level fusion

an improved SIFT feature matching algorithm is proposed. Firstly the algorithm in the feature extraction process with Harris corner detector and picks out robust points; Followed use of 48 dimensional vector based on a circular window to dimension reduction and the feature points are refined by the geometrical consistency of the matching feature points

to improve the efficiency of the algorithm. Finally

the overlapped area linear transition fusion algorithm of image smoothing the transition to eliminate the splicing gap. The experiment verifies the robustness and rapidity of the proposed method.
